This may be a language problem, but Win Explorer is the folders icon on the taskbar. Right click it to see the flyout.
Do you have a listing for Tablet PC in your Start Menu, All Programs, Accessories, Tablet PC? If you do not have that or the Snipping Tool in the Start menu, try going to Control Panel, Programs and Features, Turn Windows Features on or off, and select Tablet PC Components. Again, I am not sure this will help but you might try.
